**FastAPI** verwendet diese *vorübergehende* Response, um die Cookies (auch Header und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den `Response`-Parameter auch in Abhängigkeiten deklarieren und darin Cookies (und Header) setzen.

## Eine `Response` direkt zurückgeben

**FastAPI** will use that *temporal* response to extract the cookies (also headers and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare the `Response` parameter in dependencies, and set cookies (and headers) in them.

## Return a `Response` directly

You can also create cookies when returning a `Response` directly in your code.
